I checked out the CLE Web site. Pricy is right! I don't really need something that accurate, I just want an upper with carrier etc. that I can run ten rounds thru without it doing the Jam Jam boogie. I'm working on making fast double taps to a torso target at up to 50 yards using a holo sight. If it can group 4" at 50 yds that's good enough. I may try a Ciener kit and an old A1 upper. If the barrel leads up I can live with it. I've got a Ruger 10/22 that I could mount a holo on also. Different feel than the AR but getting used to the sight is what's important right now. When I'm more confident I'll switch back to 5.56mm. Thanks for the advice.
